“Mrs. Deline evidently planted these weapons here for someone else to use,” Jerry remarked. “We’ll put them back just as they were.”

“Put them back!” Penny echoed. “Why, Jerry, wouldn’t that be playing right into their hands? Shouldn’t we destroy these things?”

“No, it’s much wiser to have the place watched.”

Light dawned upon Penny. “Oh, I see!” she exclaimed. “In that way you hope to learn Mrs. Deline’s accomplices!”

“Exactly.”

Jerry replaced everything in the box which he carefully buried in the sand. Then he obliterated all freshly made footmarks.

“It may be necessary to watch this place for days,” he said thoughtfully.

“And what of Mrs. Deline?” Penny asked. “Will she be allowed complete freedom?”

“That’s for my superiors to decide. It seems to me, though, that more is to be gained by allowing her to remain at liberty than by arresting her.”

“I’m all for jail myself,” said Penny.
